XMPPFramework:尝试更新 VCard 上的昵称 [英] XMPPFramework: Trying to update nickname on VCard

问题描述

这个问题就像它的标题一样简单:我正在尝试更新他的 VCard 上的用户昵称，但我不能.我正在使用此代码:

This question is as simple as its title says: I'm trying to update a user nickname on his VCard but I cannot. I'm using this code:

dispatch_queue_t queue = dispatch_queue_create("queue", DISPATCH_QUEUE_PRIORITY_DEFAULT);
    dispatch_async(queue, ^{
        XMPPvCardTemp *myVcardTemp = [[[self appDelegate] xmppvCardTempModule] myvCardTemp];
        [myVcardTemp setNickname:@"a_nickname"];
        [[[self appDelegate] xmppvCardTempModule] updateMyvCardTemp:myVcardTemp];
    });

我无法想象为什么这段代码不想在同一段代码中工作，但更新照片却像魅力一样工作:

I cannot imagine why this piece of code don't want to work while the same piece, but updating photo, is working like a charm:

NSData *imageData = UIImagePNGRepresentation(anImage);
        dispatch_queue_t queue = dispatch_queue_create("queue", DISPATCH_QUEUE_PRIORITY_DEFAULT);
        dispatch_async(queue, ^{
            XMPPvCardTemp *myVcardTemp = [[[self appDelegate] xmppvCardTempModule] myvCardTemp];
            [myVcardTemp setPhoto:imageData];
            [[[self appDelegate] xmppvCardTempModule] updateMyvCardTemp:myVcardTemp];
        });

任何帮助将不胜感激...这让我发疯

Any help would be appreciated... this is driving me crazy

注意:我使用 OpenFire 作为 XMPP 服务器

NOTES: I'm using OpenFire as XMPP server

这是当我尝试更新昵称时服务器返回给我的节

And this is the stanza the server returns me when I'm trying to update the nickname

RECV: <iq xmlns="jabber:client" type="result" from="7db55e68-cb18-4826-befd-0eb9269637aa@000.000.000.000" to="7db55e68-cb18-4826-befd-0eb9269637aa@000.000.000.000/2cfc4f88"><chat_jorges xmlns="vcard-temp"><NICKNAME>chat_jorges</NICKNAME></chat_jorges></iq>

(我将服务器的 ip 更改为 000.000.000.000)

(I changed my server's ip for 000.000.000.000)

推荐答案

我完全错了，不要读这个

EDIT : I WAS TOTALLY WRONG DON'T READ THIS

其实我在看XMPP的源码的时候，就想知道它是怎么设置值的.在 XMPPvCardTempBase.h 中:

Actually when I read the source code of XMPP, I wonder how it could set a value. In XMPPvCardTempBase.h :

#define XMPP_VCARD_SET_STRING_CHILD(Value, Name) NSXMLElement *elem = [self elementForName:(Name)];
//it looks like a get and not a set??

在 XMPPvCardTemp.m 中:

And in XMPPvCardTemp.m :

- (void)setNickname:(NSString *)nick {
    XMPP_VCARD_SET_STRING_CHILD(nick, @"NICKNAME");
}

也许某处有 KVC 之类的东西......你能在源代码中试试这个吗:

Maybe there is something as KVC somewhere... Can you try this in the source code:

 - (void)setNickname:(NSString *)nick {
       XMPP_VCARD_SET_STRING_CHILD(nick, @"NICKNAME") = nick ;
   }
